TL;DR: Indium(III) chloride-catalyzed, microwave-assisted Ferrier rearrangement of different per-O-acetyl glycals leads to an efficient synthesis of 2,3-unsaturated C-glycosides in good to excellent yields.
29 citations
TL;DR: 19-norvitamin D A-ring phosphine oxide 5 was synthesized by a new sequence mode starting from D-glucose as a chiral template and achieved in an 18% overall yield by this novel cost-effective method.

TL;DR: Belghiti et al. as mentioned in this paper decrivons dans de ce travail la synthese de grands glycophanes par couplage oxydant d'ethers acetyleniques (reaction de Glaser) de glycosides symetriques, eux-memes obtenus par une double reaction de Ferrier sur le d -glucal.
